Del Col

HIP 30277 · HD 44762

A real star from the HYG catalog in the constellation Columba.

234.0 light-years away Apparent magnitude 3.85

G-type: a sun like ours

Its spectral type is G7II: the Sun's own class: roughly 5,000–6,000 °C surfaces and ~10-billion-year lifetimes. From its measured color, its surface temperature is roughly 5,112 K (4,839 °C), an estimate computed from the catalog's color index.

How far away is it?

It lies about 234 light-years away (71.7 parsecs, from its measured parallax). The light reaching Earth tonight left it around the year 1,792.

How powerful is it?

Its computed luminosity is about 129.3 times the Sun's output (derived from its brightness and distance).

Can you see it?

At apparent magnitude 3.85, it is an easy naked-eye star under any reasonable sky. It favors southern observers.

Everything above is computed from the catalog’s measured values for this star. Where a value is missing, the statement is omitted rather than guessed.
